The cobra rear bumper was on the car when I bought it. I'm relatively sure he got it from American muscle. Google them and you can find them everywhere. Roughly $500. And the GT stock exhaust fits perfectly, just a little low. Adjusting the hangers fixes that in like 20 mins.

This last pic has a bit of a story behind it. She had another '04 vert before this that she really loved. One day she was driving through an intersection when an 87 year old woman ran a red light and, literally, ripped the front of her car off. He boyfriend is a mechanic and salvaged the 40th anniversary badge and attached it to the dash as a surprise for her.
